Proposed trade of Justin Upton and David Holmberg (Lefty Starting Prospect) for Norris, Lowrie, Wesley Wright, and Paul Clemens. In this trade, Arizona fulfills all of their off-season goals: upgrade at SS, experienced SP, and LH RP on the cheap. Dbacks also rid themselves of Upton's contract which calls for $10M in 2013, $14M in 2014, $15M in 2015. The Astros pick up a young bonafide CF with speed and power coming off an average year and a Lefty SP prospect. Upton on the trading block due to expected performance, costs and issues with DBacks upper management.
